I would like to ban the ability to trim the "end fences" or "T foil INDEPENDANT" of the blade while sailing.

The big cost in this is the development of a double twist grip (or other method) to allow you to trim each T foil independantly; The 3K GBP is an approximation based on the 2K to convert a standard Moth to dual foil (moths have foils on the plate and rudder; the plate foil is controlled via a prodder in front of the boat and is fairly simple. The rudder control is changeable manually and is the complex part. I believe a "independant rudder" control for a catamaran will be complex and expensive to make and provide an immence advantage once done.

I do not want to ban the current T foils as I firmly believe they offer an andvantage at limited cost or handling penality, I also do not want to bad the adding of packing behind the rudders in order to trim them correctly. It would be impossible to control and someone has to make another boat trim decision before starting the race (just as setting the rig tension which is currently in the class rules).

The proposal is to solely ban a development that will be

a, Costly
b, If allowed make all current F16 designs obsolete and require all current boats to adopt this at significant cost.




Regarding the mast tip weight rule, I don't believe removing the rule will make a SIGNIFICANT difference - it will not make boats obsolete overnight, but the rule does limit who can sail the boat. We have a rule that by measuring the tip weight, we limit who can sail the boat single handed.
